Theoretically, if a person or a country had an unlimited amount of a resource, then that person or country would:
a. have to place limits on its use.
c. run out of it.
b. not have to make a choice on how to use it.
d. have to worry about supply

An unlimited amount means that there would always be more of it: so they can't run out of it, there will always be more! and since they can't run out of it, they don't have to worry or make choices - they can just use it without any limits and thinking about it.

So the correct answer is
a. have to place limits on its use.

It could be anything, recent improvements in technology/telecommunication/internet have increased the pace of globalization.generally, it has something to do with technology. globalization means that people around the world are brought together through technology which speeds things up. so maybe some of those options could be correct. : )
